Abstract

Several decades have passed since Gordon Allport s (1935) famous statement that the concept of attitudes is the single most important social psychological notion, and his statement rings as true today as it did then. The volumes on attitudes and attitude change continue to mushroom (see Albarracfn, Johnson, Zanna, & Kumkale this volume; Chaiken & Trope, 1999; Haddock & Maio, 2004; Olson & Maio, 1999; Petty & Krosnik, 1996) as does novel theoretical and empirical research on various aspects of attitude formation and change (e.g., Kruglanski & Thompson. 1999; Lord & Lepper, 1999; Schwarz & Bohner, 2001; Wilson, Lindsey, & Schooler, 2000).
